Mike Olsen, a.k.a. Danheim, provides some insight as to how the album was made:

“All sounds and instruments, in the death part of the song, were recorded and made from dead or decayed objects and materials, even real human bones were recorded and used in the song. The song is six minutes long and starts with Kvikr (life), then slowly moves into the Dauðr (death) part in the middle of the song around the three minute mark. At that point, all living things are removed and replaced with recordings or sounds of dead objects.”
